patch cleaning up the code

removed the unnecissary variable $tmp_line as it is unnecissary and don't add
to the logic of the code, moved up the attribute code instead in it's place and
use the variable $line again instead in the rest of the block, which for me
makes more sense.

Applied in r18160.
